A scientist has 100 milligrams of a radioactive element. The amount of radioactive element remaining after t days can be determi

grandymaker [24]

The mass of the first shipment at time t is
$m_{1}=100( \frac{1}{2} )^{ \frac{t}{10}}$

The mass of the second shipment at time t is
$m_{2}=100( \frac{1}{2} )^{ \frac{t-3}{10} }$

At time t, the ratio of m₁ to m₂ is
$\frac{m_{1}}{m_{2}} = \frac{100}{100}. \frac{(1/2)^{t/10}}{(1/2)^{(t-3)/10}} \\ = \frac{(1/2)^{t/10}}{(1/2)^{t/10}}. \frac{1}{(1/2)^{-3/10}} \\ = (1/2)^{3/10} \\ = 0.8123$

Therefore as a percentage,
$\frac{m_{1}}{m_{2}} =100*0.8123 = 81.23 \%$

Answer: B. 81.2%

A town recreation hall needs to build a ramp. The height of the ramp must be 2 ft. The ramp will start 6 ft from the door. To th

zimovet [89]

Answer:

6.32 feets

Step-by-step explanation:

Given that:

Height of ramp = 2 feets

Length of base = 6 feets

Length of ramp = l

Using Pythagoras rule :

Hypotenus = sqrt(opposite² + adjacent²)

Length of ramp = sqrt(height of ramp² + length of base²)

l = sqrt(2² + 6²)

l = sqrt(4 + 36)

l = sqrt(40)

l = 6.3245

Length of ramp = 6.32 feets

James used substitution to solve this system of equations which equation could be the result of his first step?

vaieri [72.5K]

Answer: OPTION D.

Step-by-step explanation:

<h3> The compete exercise is: "James used substitution to solve this system of equations. Which could be the result of his first step</h3><h3> $\left \{ {{2x+3y=12} \atop {y=x+1.5}} \right.\\\\\\A.y=2x+3y\\B.y=2x+3y+1.5\\C.2x+3x+1.5=12\\D.2x+3(x+1.5)=12$ "</h3>

Given the sytsem of equations:

$\left \{ {{2x+3y=12} \atop {y=x+1.5}} \right.$

1- Solve for one of the variables from any equation and substitute it into the other equation.

2- Solve for the other variable in order to get its value.

3- Substitute this value back into one of the original equations. and find the value of the other variable.

In this case youu can observe that the second equation is already solved for "y", therefore, in order to use the Substitution Method, the first step is: Substitute the second equation into the first one.

Therefore, the equation that could be the result of James' first step is:

$2x+3y=12\\\\2x+3(x+1.5)=12$
